What's the difference between Paris Hilton and a cow?

Cows are ruminants, meaning that they have a digestive system that allows use of otherwise indigestible foods by regurgitating and rechewing them as "cud". Paris Hilton, on the other hand, is a human being. Therefore, her stomach digests the bolus (masticated food) only after it has exited the oesophagus into the body of the organ, where it is digested into chyme and then passed through the pyloric sphincter into the duodenum.
